some headers were not including port_def.inc
some headers were not declaring extern "C"
some headers were backing out of the above in the wrong order

Now that 'size' has been renamed as 'capacity' we are free to rename 'len' as
'size', so upb_Array_Size() is actually returning the 'size' field.

The current field/function names for upb_Array are quite confusing.
We will fix them in two steps, this being the first step.

It turns out that forward-declaring:
struct foo;
is redundant when combined with:
typedef struct foo foo;
Which is exactly what we were doing in the generated upb code. So, simplify it!

Lots of changes but it's all just moving things around.
Backward-compatible stub #include's have been provided for now.
upb_Arena/upb_Status have been split out from upb/upb.?
upb_Array/upb_Map/upb_MessageValue have been split out from upb/collections.?
upb_ExtensionRegistry has been split out from upb/msg.?
upb/decode_internal.h is now upb/internal/decode.h
upb/mini_table_accessors_internal.h is now upb/internal/mini_table_accessors.h
upb/table_internal.h is now upb/internal/table.h
upb/upb_internal.h is now upb/internal/upb.h

The cross-compiling Python tests rely on our non-public Docker image, so disable those tests if the PR is coming from an external contributor (otherwise the jobs will fail).
Also modified the Bazel tests to use a read-only cache for external contributors.

The previous change did not have the desired effect, because the generated code uses the class named "Message" instead of "CMessage."
There was no real need to use the class "CMessage" instead of "Message." The new name is simpler and will make the previous change work.

After some debugging I was able to determine that the Win32 DLL was failing to load libgcc_s_sjlj-1.dll. If we statically link libgcc instead, there should be no runtime dependency on libgcc.

upb has traditionally returned 16-byte-aligned pointers from arena allocation. This was out of an abundance of caution, since users could theoretically be using upb arenas to allocate memory that is then used for SSE/AVX values (eg. [`__m128`](https://docs.microsoft.com/en-us/cpp/cpp/m128?view=msvc-170), which require 16-byte alignment.
In practice, the protobuf C++ arena has used 8-byte alignment for 8 years with no significant problems I know of arising from SSE etc.
Reducing the alignment requirement to 8 will save memory. It will also help with compatibility on 32-bit architectures where `malloc()` only returns 8-byte aligned memory. The immediate motivation is to fix the win32 build for Python protobuf.
